Yes, yellow attracts many harmful insects, like gnats and flies. Rarely do I have a bee get stuck on this. This is my actual caution sign that I coated with sticky gel. The insect sticky gel can be purchased through the internet or at some garden stores. It may be referred to as something to keep birds away from an area.
It is called Tangle Foot. You can use any glossy yellow surface for this insect trap. These caution signs work great! They are stable and can easily be attached to posts or fences. You can remove the bug-filled gel with a putty knife, but I advise using gloves. Then just apply some more to the surface of the sign.
You can attach the sign or other glossy plastic yellow material and then coat with the sticky gel. It doesn’t wash off in the rain and stays on through many seasons. I would suggest not holding or handling a coated surface and then trying to attach it to your desired place for it. You can get this stuff all over you. Even just on your fingertips is an annoying situation. I would suggest wearing disposable gloves for this step.
If you get it on your hands, regular soap of any kind will not take it off. I use detergent for this. Basic laundry detergent works. It will dry out your hands if you use it too much, but it’s the only way I have found to take it off. Even rubbing alcohol didn’t work very well.
This sticky gel is similar to the sticky mouse traps. If anyone of you have ever stepped in one of those, you know what I am getting at. It’s almost impossible to get that stuff off your shoes, and takes a lot of work to do so.

Or use this sticky gel on a glossed yellow surface:
I made these traps seen here, by cutting square shapes out of a larger piece of blank yellow plastic that can be purchased at home improvement stores near the For Sale and such signs. I then simply duct taped them to plant markers and spread the Tanglefoot gel onto them, leaving some space from the edges of the square. They can now be stuck directly into one of the pots in my seedling area to catch gnats.
